But which side has the best attack?
Crespo of course worked with Mourinho at Chelsea and won a title under the manager, and thinks that the United boss will pull it out of the bag in his second season at Old Trafford.
"I think that Kenedy last season didn't play before he went on loan to Watford", Conte is quoted as saying by the Evening Standard. The defending was their weak point previous year, especially in goal, and at times it seemed as if Pep Guardiola was wondering what he had walked into.
"When you come out on top it is an unbelievable feeling to know you are the best team in the country, and you have gone through all sorts of things along the way to win that".
"He's a player who was 29-years-old last week with five years in the Premier League or so". That's a big if though... "He had a good fight against two good central defenders and I'm happy with his period and I'm happy with the way he fits into - I'm not exhausted to repeat - an fantastic group". Depth will be more important than ever. As for Spurs, Jake, Michael and Dan think they'll draw, while Peter expects Newcastle to run out winners in their first game back in the Premier League.
That may result in a similar outcome to what happened however.
And it is Chelsea fans who take the longest (7,602,098 minutes, 84,468 games) to pay off a typical mortgage as despite sharing the most valuable property tag with Arsenal fans, on average they earn more than £80 a week less than their north London rivals.
Former Manchester City pair Joe Hart and Pablo Zabaleta and star signing Marko Arnautovic, a £20 million recruit from Stoke City, could all make their competitive debuts on Sunday. Don't be surprised if this might be a final year in charge for Arsene Wenger.
It was one of the costliest moves in Europe during a summer transfer window that saw United midfielder Paul Pogba replaced as the most expensive player in football by Neymar, who joined Paris Saint-Germain for €222 million (S$355 million). "People at the club seemed to mull it over for quite a while and then out of respect for Petr and what he'd done, and the situation with [Thibaut] Courtois, they let him go".
There may well be a couple of sides, however, that aren't among the newly promoted that may struggle.
"When this season I got a call that Matic wants to play for me, he wants to come to Manchester United and he can make it happen, I thought he was the ideal player for me".
